Ethylene Vinyl Acetate Nylon

There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used.

Ethylene vinyl acetate nylon.

General description eva is a transparent thermoplastic elastomer used a lot for extruded tubing and athletic shoes. Ethylene propylene rubber epr thermo plastic olefin tpo poly methyl methacrylate pmma polyamide 6 pa6 nylon 6. Eva remains flexible at low temperatures and resists cracking. A polymer blend consisting of nylon 6 and ethylene vinyl acetate copolymer eva was compatibilized with an ethylene acrylic acid copolymer eaa.

Neither eva nor eaa are compatible with nylon. Polycaprolactam nylon 6 polycellulose acetate polycellulose nitrate polychloroprene. It shows good chemical resistance. Polyethylene vinyl acetate polyethylene acrylate copolymer.

Eva has limited application in injection molded components.

Tensile strength 1000 7500 psi. Ethylene vinyl acetate eva also known as poly ethylene vinyl acetate peva is the copolymer of ethylene and vinyl acetate the weight percent of vinyl acetate usually varies from 10 to 40 with the remainder being ethylene.

Eva ethylene vinyl acetate. The food and drug administration fda has stated that ethylene vinyl acetate is safe when used in food production packaging or transportation and it s not an especially dangerous material. The information in this chart has been supplied by reputable sources and is to be used only as a guide in selecting equipment for appropriate chemical. Ethylene vinyl acetate eva currently selected.

Ethylene vinyl acetate properties ethylene vinyl acetate is a flexible and transparent thermoplastic. Flexural modulus 8 000 13 000 psi. Ethylene vinyl acetate offers good low temperature flexibility. Eva is used in several applications thanks to the varied properties it possesses.

Ethylene vinyl acetate is a type of plastic a polymer with a wide variety of uses both residential and industrial. Check the chemical compatibility of nylon with various chemicals solvents alcohols and other products there are many forms of nylon so this is just a broad overview of general compatibility.
